TURNING DEVICE.V

SPECFICATON forming part of Letters Patent No. 696,817, dated 1, 1902.

Application iiled January 2l, 1902. Serial No. 90,654. (No model.)

To a/ZZ whom, imag concern.-

Be it known that I, GEORGE llosnn HIL- DRETH, a citizen of the United States, and a resident of Seattle, in the county of King and State of Vashington, have invented a new and Improved Turning Device, of which the following is a full, clear, and exact description.

My invention relates to a device for turning and shouldering masts, spars, posts, and analogous articles.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a side elevation of the device, Fig. 2 is an end elevation of the device, partly in section; and Fig. 3 is a partial sectional side elevation of the device with parts in a different position than that shown in Figs. 1 and 2.

A longitudinal tank 1 is provided Withcross-blocks 2, having bolt-holes 4t, Which are engaged by bolts 3, so as to secure the several parte rigidly in position. Centering devices 5 and 6 are provided for engaging the object to be turned, which object is completely supported by floating in the Water 7, contained in the tank 1. A number of uprights 8 support overhead tracks 9, provided with depending plates 10, which engage bolts 12, the bolts being secured by nuts 13, so as to be adjustable in slots 24 in the uprights 8.

A carrier-frame 14 is provided with flanged rollers 15 and travels longitudinally upon the tracks 9. From the carrier-frame depends a screw 16, guided in a block 22 and upon Which is mounted a frame 17, carrying an electric motor 18, a belt 19, and movable cutters 2O and 20. The frame is manipulated by means of handles 21 and is mounted to turn by the revolution of a turnbuckle 22L upon the screw 16. The rollers 15 and the frame 111 are engaged by rods 23, as indicated more' particularly in Fig. 2.

The log 25, Which is to be used in making the spar, mast, post, or other article, is centered upon the centering devices 5 and 6 in much the saine manner that it would be chucked in a lathe. The smooth surface 26 (see Fig. 1) shows the portion of the log which has been operated upon by the cutter-heads 2O and 20fL as the log is turned by means of the Wheel 23 in the usual manner.

The turnbuckle 22a is swiveled upon a rod 26, which is firmly secured by means of setcollars 27 2S upon a second block 22, through which said rod passes.

At 29 (see Fig. 3) is shown an overfiow for maintaining the Water 7 at a cons tant level.

The operation of my device is as follows: The log to be turned is placed in position upon the blocks 2 2 and is approximately centered by the centering devices. filled with Water, as indicated in Fig. 1, thus completely supporting the log. The centering is now made exact and the log is turned as any piece of timber is turned in a lathe. By manipulating the handles 21 and passing the-cutter-heads 20 and 20a over the surface of the log the material thereof is Whittled O after the manner of operating with a planer or a milling-cutter. The speed of the cutterheads is very great as compared with the rotative speed of the log, the two motions being entirely independent.

In cutting the body of the log the cutter 2O is preferably employed. The cutter 20 can be employed in this relation or not, as desired. For the cutting of shoulders 27, however, the cutter-head 20a is very essential, as indicated in Fig. 3. In cutting these shoulders the frame 17is turned at a right angle to the p0- sition shown in Fig. 1 and is moved laterally by the handles 21. This movement is indicated in Fig. 3.

The iioating of the log upon water renders the Weight of the log practically m'l and also lubricates the bearings or centering devices at the points where friction is likely to occur. It Will be observed,therefore, that I have invented a simple and efficient device of great utility and which can be constructed cheaply and operated by any person of ordinary intelligence.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A turning device, comprising a cutter, means for centering and rotating an object to The tank is then"- be turned, and a tank containinga liquid for floating said object While being turned.

2. A turning device, comprising means for centering and rotating an object to be turned, a tank for floating said object, and a revoluble cutter free to move bodily adjacent to said object to be turned.

3; A turning device, comprising means for centering and rotating an object to be turned, a longitudinal tank for floating said object, and a traveling` carrier having a depending arm provided with a revoluble cutter, the said carrier being free to move in a direction substantially parallel with said horizontal tank.

4. A turning device, comprising a longitudinal tank for holding liquid, longitudinal tracks located substantially parallel thereto, means for centering and rotating an object in said tank so as to float therein, overhead tracks substantially parallel with said tank, posts for supporting said tracks, means for adjusting said tracks relative to said posts, and a cutting device for operating upon the Object to be turned.

5. A turning device, comprising a longitudinal tank for holding liquid, longitudinal overhead tracks located substantially parallel to said tank, means for centering and rotating an object to be turned, a traveling carrier mounted upon said tracks and provided With a depending screw, a frame provided with a threaded member for engaging said screw and thereby adjustable relatively to said carrier, revoluble cutters mounted upon said frame and movable bodily therewith, and means for actuating said cutters.

G. A turning device, comprising means for centering and rotating an object to be turned, a tank for holding a liquid for oating said object, supports for sustaining said object independently of said means for centering and rotatingandalsoindependently ofsaidliquid, and operating mechanism for cutting the object to be turned.

7. A turning device, comprising means for centering and rotating an object to be turned, a longitudinal tank for floating said object, longitudinal tracks located substantially parallel with the general direction of said tank, a traveling carrier having a depending arm provided with a revoluble cutter for engaging the object to be turned, mechanism for actuating said cutter, and means for adjusting the position of the said tracks relatively to the position of said tank.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
